Photometric studies in hydrogen + oxygen + carbon dioxide flames. Part 1.—Metal hydroxide dissociation energies

Abstract

H₂+ O₂+ CO₂ flames offer significant advantages over H₂+ O₂+ N₂ flames as a medium for studying high temperature reactions between metal atoms and oxygen-containing flame gas molecules. The system permits second as well as third law determinations of the bond dissociation energies, D°₀(M–OH), of all the molecules GaOH(434 ± 8 kJ mol^–1), InOH(374 ± 8), TlOH(< 300), LiOH (433 ± 8), NaOH (330 ± 8), KOH (352 ± 10) and RbOH (362 ± 12). The results are consistent with a linar structure for all these hydroxides.
